'Mad Men' ACTUALLY Made A Mistake?

"Mad Men" is a show that prides itself on getting even the most obscure of its period references exactly right, but Sunday's episode made a glaring anachronistic gaffe.

In the episode, Joan Holloway (Christina Hendricks) is paid a visit by her old friend Kate (Marley Shelton) and offers to make reservations at Le Cirque, the legendary Manhattan dining institution founded in 1974 by Sirio Maccioni.
